They will handle it as they see fit, or they'll ignore it and let the ban stand as it is--but it is common for threads like these to have members give their support or criticism for the person who got banned.  I think that's how it should be, since it might influence the moderators' decisions.  There was a prominent member of the Collectibles section who got their ban overturned because of that (and their name is escaping me, but it's on the tip of my tongue).

Generally, shitposters and/or members who haven't contributed much to the forum won't get any support whatsoever.  In those cases, it gives the mods a good idea that the member should remain banned, especially if they start making up all sorts of bullshit and excuses, promises, outbursts of anger, etc.  It's rare that other members stick up for a plagiarist, but personally I think people can change and people who've broken that particular rule but have otherwise been a postitive contributor to the forum ought to at least have their case reconsidered.

Of course they don't--especially when the banned member is your typical bounty-hunting shitposter.  That isn't the case with naim027 IMO.  Anyway, we'll see what happens.
